I can take care of it — can you confirm what you want fixed here: the dependency update itself, or the "Copilot wasn't able to review any files" messages?

Fixed in 199f61a.

I updated the CI workflows to use Node.js 24 (.github/workflows/ci.yml and .github/workflows/lighthouse.yml), which resolves the build failure caused by running the updated cssnano/postcss toolchain on Node 18.

Fixed in a8a16df.

I updated src/css/index.css imports to explicit filesystem paths so @web/rollup-plugin-html can resolve them during rollup -c in CI.

[dependabot]

A newer version of cssnano exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.
